what is propagation of sound
Answers
Explanation:
The Propagation of sound. Sound is a sequence of waves of pressure which propagates through compressible media such as air or water. (Sound can propagate through solids as well, but there are additional modes of propagation).Sound waves move from the point of generation to the listener through the medium. When an object vibrates and produces sound, the particles of the medium at the point of generation begin to vibrate. This particle passes on the vibration to its adjacent/neighboring particle.

Answer:
Sound Propagation
Sound propagates through air as a longitudinal wave. The speed of sound is determined by the properties of the air, and not by the frequency or amplitude of the sound. Sound waves, as well as most other types of waves, can be described in terms of the following basic wave phenomena.
Or
Sound is a sequence of waves of pressure which propagates through compressible media such as air or water. (Sound can propagate through solids as well, but there are additional modes of propagation). During their propagation, waves can be reflected, refracted, or attentuated by the medium. The purpose of this experiment is to examine what effect the characteristics of the medium have on sound.
All media have three properties which affect the behavior of sound propagation:
1. A relationship between density and pressure. This relationship, affected by temperature, determines the speed of sound within the medium.
2. The motion of the medium itself, e.g., wind. Independent of the motion of sound through the medium, if the medium is moving, the sound is further transported.
3. The viscosity of the medium. This determines the rate at which sound is attenuated. For many media, such as air or water, attenuation due to viscosity is negligible.
